Scaling GUI Agents with Visual State Transitions

Xiangyan Liu, Kaixin Li, Haonan Wang +6

We introduce State Transition Pretraining (STP) as a new scaling axis for GUI agents. During the STP stage, we continually pretrain a unified multimodal model on visual state trans…

Diagnose, Localize, Align: A Full-Stack Framework for Reliable LLM Multi-Agent Systems under Instruction Conflicts

Guancheng Wan, Leixin Sun, Longxu Dou +10

Large Language Model (LLM)-powered multi-agent systems (MAS) have rapidly advanced collaborative reasoning, tool use, and role-specialized coordination in complex tasks. However, r…

Diffusion Language Models are Super Data Learners

Jinjie Ni, Qian Liu, Longxu Dou +5

Under strictly controlled pre-training settings, we observe a Crossover: when unique data is limited, diffusion language models (DLMs) consistently surpass autoregressive (AR) mode…

Training Optimal Large Diffusion Language Models

Jinjie Ni, Qian Liu, Chao Du +5

We introduce Quokka, the first systematic scaling law for diffusion language models (DLMs), encompassing both compute-constrained and data-constrained regimes, and studying the key…

NoisyRollout: Reinforcing Visual Reasoning with Data Augmentation

Xiangyan Liu, Jinjie Ni, Zijian Wu +5

Recent advances in reinforcement learning (RL) have strengthened the reasoning capabilities of vision-language models (VLMs). However, enhancing policy exploration to better scale…

Reasoning Does Not Necessarily Improve Role-Playing Ability

Xiachong Feng, Longxu Dou, Lingpeng Kong

The application of role-playing large language models (LLMs) is rapidly expanding in both academic and commercial domains, driving an increasing demand for high-precision role-play…
